ONE BTN BOSSES is a one-button boss-rush bullet-hell with a roguelite twist and a cracking soundtrack. You auto-circle each arena and press a single button to attack, dodge and time everything; between fights you draft cards to build a run. A short, stylish campaign of themed corporate bosses, plus an endless "rift" mode where the deeper unlocks live.

The campaign is five bosses in order (1. Clocked In1. Clocked In through 5. Buzzwords5. Buzzwords) - clear them to roll credits. Everything else lives in the rifts and the unlock grind: challenge runs like PacifistPacifist (die holding the Pacifist card), CommonerCommoner (no rare cards) and Tons of DamageTons of Damage (100+ dps), the completion sweeps CompletionistCompletionist and CompletioniSSSSSStCompletioniSSSSSSt (every level, then every level at S rank), and the big grind The GrindThe Grind (buy every ability and palette). A couple are properly hidden - RevolutionRevolution, The Forbidden OneThe Forbidden One. See each note below.

The Forbidden One

ObjectiveOptional

Hidden achievement. Collect the rare card "Fragment of Aidoxe" five times in a single rift. Each fragment you hold raises the drop chance of the next, so bank a couple early from rift rewards, then farm minibosses, rests and shops (where rares are likeliest) to stack all five.
